Dishwasher appliances generally include a tub that defines a wash chamber. Rack assemblies can be mounted within the wash chamber of the tub for receipt of articles for washing. Spray assemblies within the wash chamber can apply or direct wash fluid towards articles disposed within the rack assemblies in order to clean such articles. Multiple spray assemblies can be provided including e.g., a lower spray arm assembly mounted to the tub at a bottom of the wash chamber, a mid-level spray arm assembly mounted to one of the rack assemblies, an upper spray assembly mounted to the tub at a top of the wash chamber, and/or other spray arms, assemblies, manifolds, or devices.
Conventional dishwasher appliances are typically equipped with at least one pump for circulating fluid through the multiple spray assemblies. In addition, devices referred to as diverters may be used to control the flow of fluid received from the pump. For example, a primary diverter may be positioned within a sump of the dishwasher appliance for selectively controlling the flow of wash fluid between four supply conduits. However, certain dishwasher appliances include more spray assemblies than can be supported by the primary diverter alone. More specifically, space restrictions within the sump portion of the dishwasher often limit the number of spray assemblies that may be supported by the operation of the primary diverter. Thus, additional pumps, fluid supply conduits, and or complicated diverter assemblies are often needed to provide all spray assemblies with wash fluid.
Accordingly, a dishwasher appliance that utilizes an improved fluid distribution system would be useful. More specifically, a fluid distribution system that is capable of selectively diverting a flow of wash fluid from a fluid conduit positioned within the wash chamber would be particularly beneficial.
